Technical Data
Fibronectin (FN, Fibronectin 1, FN1, Cold-insoluble Globulin, CIG, ED-B, FINC, FNZ, GFND, GFND2, LETS, MSF)
Glycoproteins that have a key role to play in various contact processes within vertebrates such as cell attachment and spreading, cell migration, control of cell morphology, differentiation and oncogenic transformation. It is present in a soluble dimeric form in plasma, and in a dimeric or multimeric form at the cell surface and in extracellular matrix. It has a 26 amino acid signal peptide and it undergoes proteolytic processing at its N-terminus to eliminate a 5 amino acid pro-sequence (Ser-Lys-Ser-Lys-Arg). All its biological activities involve its interaction with cells and with extracellular materials like collagen, heparin, fibrin, cell surfaces, bacteria and DNA. The gene has three regions subject to alternative splicing, with the potential to produce 20 different transcript variants. Plasma FN is secreted by hepatocytes while cellular FN, made by fibroblasts, epithelial and other cell types, is deposited as fibrils in the extracellular matrix. It maps to 2q34 region of human chromosome.
